The first one wasn't pretty, but I did land it and the 2nd one I did I landed well and was able to proceed over the 3rd jump. These aren't that large, but big enough for me and everyone says start small

It took lots of tries, I mean lots.
Issues I need to address:

Taking off late

Not getting good rotation, actually landing 90* often

Need to get smaller and load my twist better

turn my head more

Might be scrubbing too much speed, not sure

I studied others a lot and they seemto go fairly slowly and it looks effortless unlike mine

But I did it and will keep practicing, impact shorts worked GREAT

if you hit the jump/bump with more speed a couple of things will happen:

you won't have to jump up with your legs as much because the speed will propel you off of the jump

you'll be going a little bigger, and will have a little more time in the air to turn the board around - and see your landing

you may have time to grab your board (or at least try) which will make you suck up your knees in the air - giving you more time

don't worry about "needing to get smaller and loading your twist" - don't need that much for 180's... instead try to concentrate on counter-rotating your body as you approach the jump, and as you are riding off of the takeoff begin your rotation with your upper body - shoulders, neck, head will initiate the spin before you even leave the lip, and your lower body will just come around.

also, practice jumping 180's and 360's in a snowboarding stance out on the lawn with no board on - it will teach you to keep your eyes open, counter rotation before the jump, etc.

funny i just started doing them the other day also... got the 3rd one ever on video and i pretty much stick them every time now.. is this about the size u are learning on also??------>>> YouTube - Jump 3

also best advice i can give u,keep in mind i am an intermediate beginner is that you should screw the jumps and learn how to ride down the mountain switch and the jump turns will come easy. i got it after like 2 tries. but if u know how to ride switch then good and i have nothing to say

I can ride switch on green runs at med speed. Still practicing switch riding only 5 tx ever snowboarding.

Yes I think the jump I was hitting is a little smaller than that, and I had a landing flat area. It also appears that you are going faster than I was.

Like everyone says start small and practice. One thing to, this was mostly at the end of the day. So I may have not had much left in the ole' tank to start. Having never done this, not sure how much "pop" I need.

You really dont need pop at all. Approach the jump like normal and pop like normal. Turn your head, shoulders, waist then the board. Honestly commitment is the biggest factor seeing you cant spot your landing. Just dont land on your edge

I go off those jumps and if you are landing on the flat tops of the tables then you are going way too slow. I usually land on the table off the first and have no problem landing on the landing of the second and if I really try I can almost clear the 3rd as that one shoots you a lot more out than up.

If you bomb those 3 you should have no problem getting a little more air. Me and my buddies do 3's off of those. More them than me. I do a lot of grabs but I still know exactly what your going off of.
